I bought a X331 off a trader on craigslist. It was leaking when I tested it. I told him to fix the leaks and I'd buy it. His guy "fixed" the leaks ... possibly. He left so much hydraulic oil all over the place that it's been hard to tell how well he fixed things. I've tried to clean/degrease it a bit, but I don't have good access to water at the site where it's at. He's supposedly warrantying this thing against leaks for a month or so. So I need to figure out whether it's in good enough shape to keep.
Most days it doesn't seem to leave any oil behind. Then one day I'll see a few drips coming from the center of the machine (the machine didn't include the skid plate over this area).
It doesn't seem to be dripping when it's running.
The swivel joint seal _seems_ to be in good shape ... It seems oil would pool in this one place on top of the seal if it was leaking, and it's dry there.
I haven't ruled out all of the fittings into the swivel joint being leak-free. Need to try and degrease those more.
If I tilt the machine up 30 degrees with the boom (creating a lot of force on the turntable), I'll see a couple of drips of thinner-than-grease maybe a little milky fluid come of out the slew joint.
The two zerks on the front and back of the slew joint. Do both of those grease the slew bearing? Or does one try to grease the slew pinion and gear? If they don't grease the gear, how does it get greased? Is there supposed to be a controlled leak coming out of the bottom of the swing motor for lubrication?
How do the pictures look? Anything alarming?
Thanks!
